A piezoelectric ceramic material having the molar compositionwhere Ais selected from the group Ca, Mg, Sr, Ba, or their mixtures, Ais selected from the group of rare-earth elements or their mixtures, Bis selected from the group Nb, Ta, or Sb or their mixtures, Bis Cu or a mixture of Cu with at least one element selected from the group Zn, Ni, Co, or Fe, and Bis Fe, and where the following applies : 0.001<=a<=0.05; 0.05<=b<=0.90; 0<=c<=0.04; 0.005<=x<=0.03; 0.5<=y<=0.55; 0.05<=z<=0.90; 0<=w<=0.5. Furthermore, an electroceramic multilayer component is described having insulating layers containing such a material. Two manufacturing methods are described for the ceramic material, metal ions being introduced as powdered oxides and/or carbonates, mixed together, and calcined to form the ceramic material, or powdered ZrO2 and TiO2 is calcined to form ZryTi1-yO2 where 0.50
